Brazing Ends: These ends are available on brass valves. The ends have a special shape to facilitate use of brazing alloys. These valves are used for higher tempera tures than solder end valves. ' 4. Solder Ends: For use. with copper tubing in plumbing, heating and air condi tioning. Should not be used at high temperatures. 5. Flared Ends: For use with light wall tubing--^either metal or plastic--and for Table 11.

The brass used in valves is similar to that used in brass pipe and contains 5 some tin and lead as well as copper and zinc. Table 11.

A flaring tool flares the tube end, and a ring nut pulls theflared tubing up against a seat on the valve. This makes a lap joint. 6. Hub Ends: Generally used for water supply and sewage piping. This type joint is used with cast iron pipe. The joint is a socket type made by inserting the pipe in the hub, then caulking with oakum. After caulking, the joint is sealed with molten lead. Valves are made of brass,, iron* steel, and to some extent malleable iron. 12 13 14 16 16 17 18 Nominal Pipe Size 1 1H 1H 2 4 5 14 Ring Joint Center to End. 46-Deg Elbow KK Center to End.
